This invention relatesfto improvements in the construction of floating vessels and has reference to but not exclusively to that class supported by the relatively shallow trans; ,verse members 13, disposed in line with the members 6; and joining the bottomgends ofof vessel especially adapted forv carrying ore fiinbulki'r The objects of the invention areto 1mprove the construction of this type of vessel in such manner asto save the ,cost of the longitudinal stringers usually employed,

sa'idmembers 6 and 13 are large'transversely 160 disposed 'stifieningmembersor brackets 11% whlle said members 6- andx'13 are joi'ned' at; their topportions by the stifleningl members 12, as shown. 14 represents t e tops to provide a construction wherein a less number 'of parts-have to be riveted or dealt with, and in general to rovlde a seaworthy construction which w1 metal for the same kind and class of vessel than has heretofore been proposed. f

With these and otherobjects in vlew, the invention "consists in the novel details of. construction and combinations of parts-more fully hereinafterdisclosed and particularly pointed out in the claims.

Referring to he accompanying drawings, forming a part of this specification, in whlch like numerals designate like partsin all the views:- a 5 Figure 1 is a diagrammatic sectional view partially broken away, taken on'the line 1'1 of Fig. 3, looking in the direction of the arrows and showing a vessel madein accord-.

relatively deep transverse frames 5 spaced from say 12 to 24 feet apart, and in between these relatively deep and strong transverse frames there are fitted the relativelyjshallow transverse frames 6'. Below said tank tops 14. there are also fitted the transverse frames 6, I so that these said shallow transverse frames (Sand 6 are made to extend respectively from near the bilge 7 up to the tank tops 14 and to the deck portions 3, as'shown.

of thetanks 10, they also-serve as deck portions above said tanks. represents ex- 1 tensions of the top '8 of the bottom tank and they constitute the bottoms of said wing tankslO. said wing tanks 10 may be a made of any suitable and. desiredlength and are-provided with transversely dispose end walls 51 shown as partiallyhroken away in Fig." 1, which end Walls are securely fitted to the-skins 1 and 9'and to the tank tops 14 said tanks .10 ver- .75

Brackets 1'6 connect the upper ends of the transverses 6 with the deck 3, while channels or other longitudinal forms 17 support the deck ina manner similar to that disclosed in my prior U-.. S. Patent #1,029,546, dated 'June' 11,, 1912. 18 representslon 'tudinal" stifl'enin -members, dis osedon eac side of the hate es of the vesse and serving to. connect the deck'with the widel spaced trans ig. 1. 19 re verses 5funder'the deck, see

stifiening member's longitudina y disposed in the bottom,;see. Fig. 2. The bottom shell 2 isfurther stiffened. by the 'lon g1tud1nallydisposedchannels'20 and the tanktop-S by'. the longitudinally disposed angle members 21 asusedin the well known d disclosed .in my 22, Fig. 2, indi cates the center keel.'-l

In addition to the 0 with each frame 6,the deep transverse memhers c ss thB in It will. .now-be clear, that this vessel is provided 'with the abovesmentioned deep said v 0 p v ing,the tom 1s further stlfi'enedby, isposing in linewith each alternate side frame 6 or in line tom tank top 8 there are disposed inner skins 9, forming inner walls of the wing effect is continued into the tanks 10-by the tanks 10 as shown. These inner skins 9 are plate members 12 that saidves'sel has the thetank tops, 14, and that their stiifening t v relatively deep and widely spaced bottom transverses 41, each alternate one. extending across the bottom of the vessel in line with said transverses 5, and that they are continued up beyond the bilges 7 and into the tanks 10 by the plates 11 as shown. It thus results that the vessel in the planes of said deep transverses '5, is completely encircled by stiflening girders, while in between the planes of sald transverses 5, there are disposed in the bottom additionaltransverse members 41, and in the sides the additional transverses 6 and 13. In addition to the abovethe longitudinal members 19, 20, 21 and 22 are disposed in the bottom and the longitudinal members 17 and 18 in the deck. The outer skin and deck plating are directly attached to the transverse and longitudinal members, and the inner skin plating 9 I is likewise attached to the members 11, 12

and 13, so practically all of this plating becomes a part of the longitudinal stiffening; It thus results that the material is so disposed in the hull as to form in efiect a plurality of transverse and longitudinally disposed girders, each of which provides amaximum of stiffness with a minimum weight of metal, and therefore a very material saving in metal over the prior ordinary constructions is effected.

In fact, in constructing a vessel according to the foregoing disclosure, should it be 7 about 580 feet long between perpendiculars,

18 maybe 2 feet, and they may I find the upper sections 6 of the transverses ma be channels 10 inches dee with 3 inc flanges, and weighing 22 s. per ft.,

while the lower sections 6 may be 12 inch channels with 3 inchv flanges and wei bin 31 lbs. per ft. The members 13 mayie 0% 10 inch channels with 3 inch flanges weighing 22 lbs. er ft., while the plates 11 ma be 3 ft. higli and 6 ft. lon and the plates 12 ma be 2 ft. high an 6 ft. long, and inc es thick. 7

The channels 20 may be 10 b 3 inches weighin 22 lbs. per ft., an t e an les 21 may be by'3 inches, weig ing 15 per foot. The vertical keel 22 may be 5% ft. deep, weighing, 23 lbs. per square foot, and the tanks 10 may be 6 ft. wide and 16 ft. high and about 72 feet long if desired. The longitudinals 19 may be spaced 12% ft. from the keel and the depth of the 10 'tudirllcalg about 20 ft. on each side of the cente i line ofthe ship. The members 17 may be located "outside the longitudinals 18 and made 1 of channels having 12 inch webs and 4 inch flanges and wei hing about 41 lbs. to the foot. They may spaced 2% ft. apart.

A modi cation at the bilge may be made without departing from the spirit of the invention. Regarding the same lon 'tudinals .70 are indicated at one side of v ig.

1, although ifintermediate transverse brackets are fitted between floors 41 at this part in lieu of these three longitudinals, the drawing would appear as shown on the opposite side of said figure.

A vessel provided with a plurality of strong deep transverse frames and beams spaced from 12 to 24: apart, with a lurality of intermediate and relatively s allow transverse frames spaced on the sides of the vessel between said dee transverse frames, and with wing tanks w ose inner walls are spaced from the sides of the vessel a distance equal to the depth of said first named transverse frames, said vessel in its sides being devoid of longitudinally disposed frames frames, said vessel in its sides bein devoid of longitudinally disposed frames, ut ro- -vided with longitudinal frames in its ttom and deck portions.

3. A cargo vessel provided with a plurality of strong deep transverse frames and beams spaced from twelve to twenty-four feet apart extending entirely around the deck portions of the vessel with a plurality of intermediate and relatively shallow transy verse frames spaced on the sides of the vessel between sai deep transverse frames; and with wing tanks whose inner walls are spaced from the sides of the vessel a distance equal to the depth of said first named transverse frames, said vessel in its sides beiigg devoid of longitudinal frames but rovid with longitudinal frames in its ttqm and deck portions.

4. A cargo vessel provided with a plurality of strong deep transverse frames and beams spaced from twelve to twenty-four feet apart, extending entirely over the deck rtions of the vessel, and partially down he sides with a plurality of intermediate and relatively shallow transverse frames spaced on the sides of the vessel between and below said deep transverse frames, and some of which extend across the bottom of the vessel; and with wing tanks whose inner walls are spaced from the sides of the vessel a distance equal to the depth of said firstnamed transverse frames, said vessel in' i'tsside being devoid of longitudinally disposed frames but provided with longitudinal frames in its bottom and deck portions.

5. A vessel provided with a plurality of strong dee transverse frames and beams spaced furtqier apart than has been heretofore customary in the same class and size of vessel, with a plurality of intermediate and relatively shallow transverse frames spaced on the sides of the vessel between said deep transverse frames, with wing tanks whose inner walls are spaced from the sides of the vessel a distance equal to the depth of said first named transverse frames, the u per ends of said wing tanks receiving t e lower ends of said deep transverse said vessel in its sides being devoid of Ion tudinally diposed frames but provided with longitudinal frames in its bottom and deck portions, and said vessel also provided with a plurality of stron deep transverse frames in said bottom in 11116 with said first men tioned deep transverse frames.
